It starts on the B5342 Ullet Road and heads north-north-west along Belvidere Road which, about halfway along the course of the route, turns north-north-eastward and becomes Devonshire Road. The buildings lining these two roads are quite grand, underlining the fact that this part of town was at one time very affluent. Behind the houses on the right-hand side lies Princes Park, a couple of entrances to which are passed before the route ends at a roundabout junction with the B5175.

Originally the road continued further along Kingsley Road to end on the A562 Upper Parliament Street. However, this section was declassified in the 2010s.
